Silver Plated Ring Mandrel. Create your own stylish rings! Use these ring mandrels with flat leather or other materials. Ball ends twist off giving you 14mm of beading space on the mandrel. The thin 1.5mm mandrel can accommodate a wide range of beads and spacers. Please note ball ends are attached to the mandrel very securely for shipping so you may need a pliers to remove them for the first time.
